Creating Scrolling Text or Running Text using ATmega16 and Shift Register 74HC595 - Fareedish's Blog

Because the stock of LEDs is abundant, around 6 thousand pieces more so I decided to make a Scrolling Text or often by many people called Running Text. 

Scrolling Text uses the column scanning method using IC Shift Register 74HC595 and row control using IC D-Latch 74537, the advantage is that if you are going to add the next block, you only need to add one IC 74537, but to connect to the next block you need 3 sheets more rainbow cables. 

And here are the Photos of the making!
